Model-Free Predictive Fault-Tolerant Control for Spacecraft Roto-Translational Relative Motion [PDF]

open access: yesفصلنامه علوم و فناوری فضایی, 2021
The problem of jointly controlling relative attitude and position of spacecraft in the presence of actuator fault is investigated in this paper. Following a description about drawbacks and limitations of the existing models and the control approaches ...

On the relativity of perceived motion [PDF]

open access: yesActa Psychologica, 1981
Perceived stability of the visual world during eye movements is traditionally explained as due to the presence of extraretinal signals, equal in magnitude to retinal signals. Motion is perceived when the two signals differ. An experiment is reported in which motion thresholds were measured during smooth pursuit eye movements.

MOTION CONTROL ANALYSIS OF TWO COLLABORATIVE ARM ROBOTS IN FRUIT PACKAGING SYSTEM

open access: yesJurnal Ilmiah SINERGI, 2021
As robots' use increases in every sector of human life, the demand for cheap and efficient robots has also enlarged. The use of two or more simple robot is preferable to the use of one sophisticated robot.

Non-inertial effects on matter motion in centrifugal model tests

open access: yesYantu gongcheng xuebao, 2021
As the major scale model test equipment in geotechnical engineering, the centrifuge has become more widely used in the fields of explosions and landslides involving high-speed movement of materials with the continuous improvement of its test capabilities.

Relative Motion in Spacetime [PDF]

open access: yesReports on Mathematical Physics, 2014
In Minkowski spacetime, we consider an isolated system made of two pointlike bodies interacting at a distance, in the nonradiative approximation. Our framework is the covariant and a priori Hamiltonian formalism of "predictive relativistic mechanics", founded on the equal-time condition. The issue of an equivalent one-body description is discussed.

Feature Point Matching Based on Multi-Scale Local Relative Motion Consistency

open access: yesIEEE Access, 2023
Matching feature points from image pairs with significant visual changes and repetitive patterns remains a challenging problem due to the presence of mismatches in the putative corresponding point sets.

Analysis of an Isolation System with Vertical Spring-viscous Dampers in Horizontal and Vertical Ground Motion

open access: yesApplied Sciences, 2020
This paper proposes a new vibration isolation mounting system, with spherical balls and vertical spring dampers, that provides seismic protection from horizontal and vertical ground excitation.

Movement of a material particle on an inclined plane all the points of which describe circles in oscillatory motion in the same plane

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
Differential equations of material particle movement on an inclined rough plane, which performs oscillatory motion in such a way that its every point describes a circle in the same plane, have been deduced. Peculiarities of relative particle movement on
